Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.
[0027] Please refer to Figures 1-3 , the present utility model provides a new technical solution: a connecting device for prefabricated building structural members, including a first component plate 1 and a second component plate 9. A connection buffer assembly is provided on the first component plate 1. The connection buffer assembly is used to connect the first component plate 1 and the second component plate 9, and includes the first component plate 1, the T-shaped side plate 2, the mounting plate 4, the hemispherical ring sleeve 7, the rubber buffer plate 8, the rubber buffer sleeve 11, the T-shaped groove 13 and the countersunk hole 14;
[0028] The two T-shaped side plates 2 in the connection buffer assembly are respectively located in the corresponding T-shaped grooves 13, and the two T-shaped grooves 13 are respectively opened on both sides of the first component plate 1;
[0029] Furthermore, a plurality of mounting holes 16 are opened on the first component plate 1, and a plurality of rubber buffer sleeves 11 are respectively arranged in the corresponding mounting holes 16, and second bolts 12 are arranged in the rubber buffer sleeves 11.
[0030] Furthermore, both ends of the second bolt 12 are respectively located in the corresponding counterbore holes 14, and a plurality of counterbore holes 14 are respectively opened on the two T-shaped side plates 2. The second bolt 12 is used to connect the two T-shaped side plates 2 and the first component plate 1.
[0031] Furthermore, the rubber buffer sleeve 11 is used to buffer the acting force when the first component plate 1 and the second component plate 9 move relative to each other. An installation plate groove 15 is opened on the surface of the first component plate 1 close to the second component plate 9, and the installation plate 4 is located in the installation plate groove 15.
[0032] Furthermore, clamping grooves 5 are opened at both ends of the installation plate 4, and second T-shaped plates 3 are fixedly connected to one ends of the two T-shaped side plates 2 close to the clamping grooves 5. The second T-shaped plates 3 are adapted to the clamping grooves 5.
[0033] Furthermore, a first installation groove 10 is opened on the outer surface of the second component plate 9, a rubber buffer plate 8 is arranged in the first installation groove 10, a first bolt 6 is bolted in the installation plate 4, and a groove 17 is opened in the rubber buffer plate 8. The first bolt 6 is located in the groove 17.
[0034] Furthermore, a hemispherical ring sleeve 7 is sleeved on the outer surface of the first bolt 6. The hemispherical ring sleeve 7 is adapted to the first bolt 6, and the hemispherical ring sleeve 7 is used to buffer the acting force on the first bolt 6 in multiple directions.
[0035] Furthermore, during use, when the first component plate 1 and the second component plate 9 are subjected to acting forces in different directions, a certain displacement rotation will occur between the provided hemispherical ring sleeve 7 and the groove 17, which enables a certain error tolerance to exist between the first component plate 1 and the second component plate 9. This avoids the situation where in the traditional method, bolts are used to connect to concrete, and such a rigid connection cracks or even collapses after being subjected to external acting forces. This error tolerance enables the building to have a certain deformation after being affected by aftershocks after post-disaster reconstruction to offset this acting force, so as to be able to have a certain anti-collapse property and avoid secondary injuries to the affected people caused by the collapse of the building.
[0036] Furthermore, the provided rubber buffer sleeve 11 enables the rubber buffer sleeve 11 to undergo elastic deformation under the tension of the second bolt 12 when the first component plate 1 and the second component plate 9 are subjected to tensile forces, thereby discharging the acting forces. This further avoids the problem that the first component plate 1 made of concrete and the T-shaped side plate 2 are prone to collapse when subjected to external forces.
[0037] Working principle: During use, when the first component plate 1 and the second component plate 9 are subjected to acting forces in different directions, a certain displacement rotation will occur between the provided hemispherical ring sleeve 7 and the groove 17. This allows for a certain tolerance rate between the first component plate 1 and the second component plate 9, avoiding the situation where, in the traditional method of connecting bolts to concrete, such a rigid connection cracks or even collapses after being subjected to external acting forces.
[0038] Furthermore, the provided rubber buffer sleeve 11 enables the rubber buffer sleeve 11 to undergo elastic deformation under the tension of the second bolt 12 when the first component plate 1 and the second component plate 9 are subjected to tensile forces, thereby discharging the acting forces.
